Your load balancer watches every connection to every service you run — which makes it the best vantage point in your infrastructure. The metrics worth watching, the patterns they reveal, and how to feed them into your monitoring platform over SNMP.
Where TLS ends determines what your load balancer can do. A decision guide to the three SSL modes — termination, passthrough, and re-encryption — and the feature, performance, and compliance trade-offs of each.
Traffic layers rarely fail loudly — they fall behind quietly. Five warning signs that the setup which got you here won’t get you further, and what the next step looks like for each.
Global Server Load Balancing steers users to the right data centre before a connection is ever made — using nothing more exotic than DNS. How it works, what it’s for, and how it fits alongside your local load balancers.
A load balancer that protects you from server failures but has no failover of its own is a liability. How active-passive HA with VRRP works, what actually happens during failover, and how to set up a pair.
Round Robin, Least Connections, weighted variants, and hash-based schedulers each suit different workloads. A practical guide to picking the algorithm that matches how your traffic actually behaves.
Free software is not free infrastructure. Where the real money goes in a DIY traffic layer — engineering hours, incident exposure, and key-person risk — and what consolidating it onto one platform changes.
Kernel-speed packet forwarding or full application-layer proxying? Understanding the trade-offs between L4 and L7 load balancing — and when to use each — saves you both latency and lost features.
Direct Server Return lets backend servers reply straight to clients, bypassing the load balancer on the return path. Here is how it works, why it matters for high-throughput services, and when it is the wrong tool.
A basic HAProxy config takes twenty minutes. Certificates, health checks, failover, monitoring, and safe change management are where the real work — and the real risk — live. There is a shorter path.
